Jack planes are large smoothing planes, often used for preliminary smoothing of wood edges. A more precise tool will be used to finish the piece. This plane’s double irons are slightly convexed to avoid marking the edges of the cut. Jack planes are usually 12-18 inches long, but can be found up to 30 inches.
